The roll I consists of a plurality of windings or convolutions, thenumber of which depend upon the purpose for which the roll is intended.The width of the roll may also vary depending upon the purpose to whichthe roll is put. The roll is usually provided with a wooden or cardboardcore 2 as illustrated in Figure 2.

Referring to Figs. 1 and 2, the tab 3 extends around the outside of theroll, with an enlarged inner end 3 located beneath the end l of theouter winding of the paper and adhesively secured thereto. The outer end3 of the tab extends right around the roll and overlaps the inner end 3*and is adhesively secured to the outer surface of the inner end of thetab 3 beyond the-end of the outer winding of the roll I. In Figure 1,the overlapping outer end is shown as not accurately registering withthe overlapped portion of the roll, in order that the construction maybe more readily understood. Theoretically there should be accurateregister, but it will be understood that commercially this will notalways be the case. By tearing the tab between the point at which itsouter end is secured to the overlapped portion and the end of the outerwinding of the roll, the tab may be broken thus releasing the roll, andall that is necessary before using the roll is to tear oiT a shortportion of the end l of the outer winding in order to remove the tabtherefrom. It will of the tab is of less width than the roll so that thefinger nail or sharp instrument may be pressed against the flat surfaceof the outer convolution of 'the roll and'engaged beneath the tab inorder to tear it.

Figure 8 illustrates a modified construction, differing only from theconstruction illustrated in Figs. '1 and 2 by the fact that the enlargedend 3 of the'tab beneath the outer convolution of the roll is muchlonger'and extends more than half way around the periphery of the roll,and is not adhesively secured in any way to the roll. The purpose ofthis is to firmly clamp or frictiona'lly hold the end of the tab betweentwo windings of the roll, while the outer end of the tab is being woundaround the roll, and secured to the overlapped part of the tab after thestrip of paper has been cut, by the method hereinafter described.

In commercial practice such rolls of paper are cutand wound from a largeroll or web of paper, the individual rolls being formed in groups organgs on a long spindle 'and'subsequently separated. It is thereforedesirable to apply the tab to :the group'or gang of rollssimultaneously, and

for this purpose the tabs are formed in strips as illustrated in Figure3 and are applied in the manner shown in Figures 4 to 6. As illustratedin Figure 3 theenlarged ends of each tab are connected to the adjacent.ta'b, but are perforated, creased or otherwise provided with a line'ofweakness at 6 so that they may be readily broken apart when the rollsare separated.

In Figure 4 'the method of inserting the tab is illustrated 'on a singleroll for the sake of simplioity. Paper comes from a large roll and iswound on the core 2 on a shaft or spindle I. When a roll of the propersize has been formed the shaft i is stopped from rotation and a rip cord8 is laid across the paper. Over the rip cord is laid the tab 3, or inthe case of a series or gang of rolls, a strip 'of connected tabs suchas shown in Figure 3. The roll is then wound around on the spindle tothe position shownin Figure 5, the end 3* of the tab being then beneaththe outer convolution of the paper. The rip cord 8 is then pulled asillustrated in Fig. 5, thus cutting the paper on the roll. The roll isthen wound further to the position illustrated in Figure 6 and the end3* of the tab is lifted up and glued to the outer surface of the tabadjacent the inner end and beyond or spaced from the end of the roll, asillustrated in Fig. 6. Of course, the winding of the tab 3 may becompleted by applying adhesiveto the end 3 thereof and then turning theroll around further until the end 3 of the tab comes in contact With theouter surface of the other end of the tab and is adhesively securedthereto.

It will be understood that in the operation above described andillustrated the roll will be suitably supported so as to press the tabagainst the outside of the roll as it is turned. Figure '7 illustratesdiagrammatically in side elevation how the roll is wound. The main roll9 is mounted on a spindle I!) which freely rotates. The web of paper iscarried through a number of guide rolls and between a cutting roller I lwhich has annular blades and a roll supporting roller I 2 which hascorresponding grooves, which do not show in the drawing. This cuts theweb into a plurality of narrow strips of the required width, and theseare carried over the supporting roll I 2 and the supporting roll |2"=and around a spindle l3 on which is mounted the core 2. A verticallymovable pressure roll l4 bears down on the roll as it is being wound.The cutting roller Id, the supporting rollers l I and I2, the spindle l3and the pressure roller [4 are all positively driven by suitably timedgearing from the same source of power. Each individual roll I has aseparate core 2, all of which are contiguously mounted on the spindleI3. When it is desired to insert the strip of tabs the various driverollers are stopped and the pressure roller I4 is raised. The spindle l3may then be turned by hand for the operation of applying the tabs andcutting the end of the roll.

The tab illustrated in Fig. 8 is applied in a similar manner to the tabshown in the other views except that it is not adhesively secured to theroll at its enlarged end 3 The enlarged end is placed in the bitebetween the roll and the unwound portion of the strip. The tearing stripis placed between the tab and the unwound portion of the strip of paper.The roll is then turned carrying the end of the tab and cutting stripwith it for one complete rotation until the extreme end of the tab comesbetween the roll of paper and the supporting roller l2. This clamps thetab in position while the roll strip is cut and the end 3' of the tab isadhesively secured to the body of the tab beyond the cut edge of theroll.

When the gang of rolls have been wound and the tabs applied thereto,they are removed from the spindle and may be readily broken apart, thetabs tearing along the line 6.

It will be observed that the enlarged end 3 of the tab extends to and isflush with the edges of the roll. This is an important feature of theinvention for two reasons. In the first place, it serves to position thetab relative to the sides of the roll, so that the narrower portion ofthe tab, the edges of which are parallel with the edges of ithe enlargedportion of the tab, will, when wound around the roll, accurately overlapthe other end of the tab in order that it may be secured to the outerportion thereof.

A further reason why this construction is important is that in the caseof applying a strip of tabs to a gang of rolls, the individual tabs maybe connected between each roll, and may be applied in a strip instead ofindividually.

What we claim as our invention is:

1. The combination with a roll of paper, of an elongated paper tabhaving an enlarged inner end of the same width as the roll, said innerend of the tab being adhesively secured to the under face of the end ofthe roll with its edges substantially flush with the edges of the roll,the main portion of the tab being of less width than the roll with edgessubstantially parallel with the edges of the enlarged inner end, saidmain portion of the tab extending around the outermost winding of theroll and the outer end of said tab overlapping the inner end and beingadhesively secured to the outer surface of the overlapped portion of thetab.

2. The combination with a plurality of tightly wound rolls of paperarranged end to end, of a plurality of elongated paper tabs each havingan enlarged inner end of the same width as a roll, each inner end beingsecured to the roll and having its edges flush with the edges of theroll and joined to the adjacent edge of the adjoining tab, the mainportion of each tab being of less width than the roll and extendingaround the outermost winding of the rol the inner end of the tab beingfrictionally held beneath the end of the said outermost winding of theroll, and the outer end of each tab overlapping the inner end thereofand secured to the outer surface thereof beyond the end of the roll.

3. The combination with a plurality of tightly wound rolls of paperarranged end to end, of a plurality of elongated paper tabs each havingan enlarged inner end of the same width as a roll, each inner end beingadhesively secured to the roll and having its edges flush with the edgesof the roll and joined to the adjacent edge of the adjoining tab, themain portion of each tab being of less width than the roll and extendingaround the outermost winding of the roll, and the outer end of each taboverlapping the inner end thereof and secured to the outer surfacethereof beyond the end of the roll.

4. The combination with a plurality of tightly wound rolls of paperarranged end to end, of a plurality of elongated paper tabs having theirinner ends secured to the rolls, the inner end of each of which is thesame width as a roll and joined to the adjacent edge of the adjoiningtab, and the outer end of each tab overlapping the inner end thereof andsecured to the outer surface thereof.

5. The combination with a plurality of tightly wound rolls of paperarranged end to end, of a plurality of elongated paper tabs, havingtheir inner ends adhesively secured to the outermost windings of therolls, the inner end of each of which is the same width as a roll andjoined to the adjacent edge of the adjoining tab, and the outer end ofeach tab overlapping the inner end thereof and secured to the outersurface thereof.
